Patent GB-811900-A (GB)
Title: Improvements in means for automatically regulating the cooling action of an engine-cooling radiator
IPC: F01P7/04
Filed: 1957-03-04
Abstract: 811,900. Cooling engines. VOITH, G.m.b.H., J. M. March 4, 1957 [March 2, 1956], No. 7110/57. Class 7(2) [Also in Group XIII] In a cooling system for an internal combustion engine, in which hot engine coolant liquid is cooled in passing through a radiator over which cooling air is blown by a fan and in which louvres are provided to regulate the air flow across the radiator, a control device is actuated by the temperature of the engine coolant liquid such that as a predetermined minimum temperature of the liquid is exceeded, firstly the louvres are fully opened and only on a further rise in temperature of the liquid is the fan brought into operation, the fan speed being increased as the liquid temperature rises. When the liquid temperature starts to fall, the fan speed is gradually reduced with the fall in temperature until the fan ultimately is stopped and only thereafter are the louvres closed. In the form shown a fan 5 and louvres 2 are associated with the cooling radiator 1 of a Diesel engine, and are controlled by a thermally sensitive element 13 located in the duct 1c by which hot liquid from the engine passes to the bottom header 1a of the radiator. As the temperature of the liquid in duct 1c rises resultant expansion of liquid in the element 13 acts upon a piston 12 moving the same against the action of a return spring 14. thereby allowing the louvre actuating piston to be acted upon and lifted by air pressure from a duct 21 whereupon the louvres 2 are at once fully opened. Further movement of the piston 12 in the same direction on a further rise in the temperature of the liquid in pipe 1c, causes collar 18 to act on abutment 18a of a sleeve 17 and to move the sleeve in the same direction as the piston is moving. Such movement causes rotational movement of a toothed wheel 19b which moves the scoop tube 10 of a fluid coupling to a position in which the fan commences to rotate. Further movement of the piston 12 then causes an increase in the speed of the fan. If the temperature of the liquid in pipe 1c commences to fall the piston 12 moves in the opposite direction under the influence of return spring 14, the fan speed being decreased and the fan ultimately stopping, before the louvres are closed.

Filed: 1918-05-01
Abstract: 116,272. Graham, R. May 28, 1917, [Convention date]. Malt and malting; malt extracts and compositions.-In carrying out a process for preparing bread, biscuits, and the like, malted wheat is used. This may be malt prepared by any usual process, but is preferably malt prepared by steeping soft wheat at about 60-70‹ F. and then slowly germinating it till the acrospire is about two-thirds of the length of the grain. This process takes from 10 to 17 days. The malted grain is then treated in a kiln with dry air heated to about 160-190‹ F., and is next stored in air-tight, bins &c. for from 6 weeks to 3 months to mellow or ripen, after which it is ground. The main supply of grain, which should be a strong kind, high in gluten constituents, is milled, and the middlings and bran therefrom are combined and mixed with a quantity of the malted product and with water to form a soft paste. The mixture is then heated to about 100-150‹ F. for from 12 to 36 hours with occasional stirring. The product obtained, after drying for about 12 hours at 130-150‹ F., may be used as a finished breakfast food product. The superior white, spring clear, and low grade milling fractions of the flour from which the bran &c. had been removed, are now acted upon, preferably separated, by yeast at about 81‹ F., to form sponges, and the sponges obtained are mixed together and with the soft paste previously obtained, salt and water to form a dough. When ripe, the dough is cut up, proved and baked in a slow oven at about 350‹ F., decreasing to about 290‹ F. for from 3¢ to 4 hours to form the desired bread. The invention is stated to be applicable to treating all kinds of cereals, and pulse.

Patent GB-1375311-A (GB)
IPC: G04F3/06
Filed: 1972-02-17
Abstract: 1375311 Time switches GULF & WESTERN INDUSTRIES Inc 17 Feb 1972 [22 July 1971] 7393/72 Heading H1N [Also in Division F2] A time delay switch comprises a first clutch member angularly fast with but axially movable along a drive shaft between a first non-engaging position and a second engaging position with a second clutch member which is rotatably mounted on said drive shaft; means for selectively shifting said first clutch member; a switch; a cam member movable by said second clutch member between first and second positions to actuate said switch; drive means for said shaft; and means biasing the cam member in the opposite direction to the drive by the clutch member, whereby when the first clutch member is in said second engaging position the cam member is driven to its second position and when the first clutch member is in said first non-engaging position the cam member is moved by said biasing means back to its first position. As shown, a first clutch member 62 is axially movable but angularly coupled to a drive shaft 22 by mating hexagonal surfaces (Fig. 5, not shown). The shaft 22 is coaxially journalled in, but angularly independent of, a shaft 30 of a time-interval setting knob 24, and is driven by a synchronous motor (20, Fig. 1, not shown). A coil spring (88, Fig. 6, not shown), around shaft 22 urges member 62 to the right, but a spring 118 acting on the armature lever 112 of a solenoid 68 is effectively stronger and by means of a forked lever 64 normally holds member 62 to the left, as shown. On energization of electromagnet 68 the clutch member 62 is allowed to move to the right and a serrated surface engages a similar surface 46 of a rotary cam member 42 freely journalled on shaft 22. A return spring 50, which normally holds an arm 44 carried on cam member 42 against an adjustable bracket 34, is thus stressed by rotation of cam member 42 until two adjustable screws 60 on arm 44 actuate respective switches (130, 132, Figs. 2, 4 and 5, not shown), whereupon one of the switches de-energizes electromagnet 68, the clutch is released and spring 50 restores cam 42 to its initial position determined by bracket 34. Bracket 34 is settable by knob 24 which thus determines the time interval before actuation of the switches. A knob 26 serves to lock knob 24 in its preset position. It is stated that by simple alteration of the linkage between levers 112 and 64 the clutch may be normally engaged and energization of electromagnet 68 then disengages it. Figs. 9, 10 and 11, disclose a slightly simplified embodiment without the external setting control knob.
